Gudikallu, a small town in the Anantapur district of Andhra Pradesh, India, sits at coordinates 15.7441°N, 77.4760°E. The terrain is characterised by undulating plains typical of the Rayalaseema region, a semi-arid plateau. The town’s elevation is relatively modest, contributing to limited natural dispersion of pollutants. Gudikallu is not directly adjacent to a major body of water, though smaller seasonal streams and tanks are present, influencing local microclimates. The surrounding landscape is predominantly agricultural, with significant cultivation of groundnuts, cotton, and other dryland crops. This agricultural activity, while vital to the local economy, contributes to particulate matter pollution through dust from land preparation and harvesting. A gradual urban-rural gradient exists, with smaller villages surrounding Gudikallu. The proximity to larger industrial centres like Hindupur, approximately 60km to the north, introduces the potential for long-range transport of pollutants. The town’s location within a rain shadow region exacerbates the effects of drought and contributes to dustier conditions. The prevailing wind patterns, influenced by the topography, play a crucial role in pollutant dispersal, often channeling air towards the town from surrounding agricultural lands and potentially from industrial sources. This geographical setting creates a unique set of challenges for maintaining good air quality in Gudikallu.

Gudikallu experiences a distinct tropical climate with a pronounced dry season and a monsoon season. Air quality generally worsens during the pre-monsoon months of April and May. Rising temperatures create unstable atmospheric conditions, trapping pollutants near the ground. Dust from agricultural activities is also at its peak during this period, significantly increasing particulate matter concentrations. The monsoon season, arriving in June and lasting through September, offers temporary relief. Rainfall washes away dust and suppresses particulate matter, leading to improved air quality. However, increased humidity can promote the formation of secondary pollutants. October and November see a gradual return to drier conditions, with air quality declining as dust levels rise again. Winter months, December to February, are generally the most favourable for air quality, with cooler temperatures and calmer winds aiding in pollutant dispersion, though temperature inversions can occasionally trap pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the hot, dry pre-monsoon months. Monitoring local weather patterns and agricultural practices is crucial for anticipating pollution spikes. Avoiding peak traffic hours and using respiratory protection when dust levels are high are recommended preventative measures.
